HEADLIGHT DEFLECTOR DEVICE.

Application filed June '29, 1928. Serial No. 648,507.

To all whom it may concern:

Be it known that I, CHARLES A. HART- MANN, a'citizen of the United States, residing at San Antonio, in the county'of Bexar and State of Texas, have invented certain new and useful Improvements in Headlight Deflector Devices, of which the followingis a specification, reference being had therein to the accompanying drawings.

This invention relates to a headlight deflector device, and the object of the invention is the construction of a simple and eflicient shutter device for a lamp or a headlight. preferably for a motor vehicle.

With this and other objects in View, my invention comprises certain novel combinations, constructions and arrangements of. .parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a vertical, central, sectional view of a. device constructed in accordance with the present invention shown in a lamp or headlight.

Figure 2 is a view, in front elevation, of a device constructed in accordance with the present invention, whereas Figure 3 is a view in side elevation of the same.

Figure 4 is a perspective view of the primary plate of the shutter device. while.

Figure 5 is a fragmentary view of the same.

Referring to-the drawings by numerals. 1 designates the casing; 2 is the reflector, and 3 is the lamp 'or the headlight. The reflector 2 is provided with an annular groove 4 formed upon its outer face, in which groove is placed a packing 5 that bears against the 7 glass lens 6. The lens 6 also bears against the front of the shutter device 7, and against the annular cap 8.

Theshutter device 7 comprises a ring-like body 9 which is provided with an annular flange 10 on its outer edge. The primary bladell and auxiliary blades 12 are supported upon the ring-like body 9 to reflect the rays from lamp 3 downwardly upon the roadway. The auxiliary blades 12 as well as the primary blade '11 are beveled at their ends as at 13, Figs. 4 and 5, to fit the contour of the inner face ofythe body 9. Each 'blade is provided at its ends with tapering spurs 14 that extend through the.

body 9 and are bent at an angle to the body (Fig. 3) for holding the blades in position.

The primary blade 11 comprises the body 15 having a downwardly-extendin center bill 16. that affords a greater sur. ace for the rays of the lamp 3 to strike against, so as to prevent the glare of headlights striklng against the face, orblinding the vision, of the chauffeur in an approaching motor vehicle.

By-reason of the simple construction of the blades they can easily be assembled with the body 9 and fastened in position at a minimum cost; furthermore, if one of the blades should become injured or deficient it can be easily removed and anew blade subsituted therefor.

The ring-like body 9 is split, at 17, and 7 its overlapping ends are fastened together by suitable fastening means, for instance,

by rivets 18.

WhileI have described the preferred embodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and I therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claim.

WhatI claim is:

In a device of the class described, an open body. light deflecting strips extending transversely in said body for directing light downwardly and outwardly through the body, said strips being spaced'verticallyin said body with one strip positioned a greater distance from the strip below it than it is from the stripabove it, and a light conceal.

. ing element extending downwardly from the intermediate portion of the last-mentioned strip across the relatively wide space and adapted to be positioned in front of a source.

of light when said body is positioned in operative relation to a lam body.

In testimony whereof I ereunto afiix my signature.

CHARLES A. HARTMANN.
